Voclosporin: A Novel CNI

• Novel CNI developed as a structural change from cyclosporine A, incorporating a single carbon extension with a double-bond

• Voclosporin has a consistent dose response potentially eliminating the need for therapeutic drug monitoring

• 4x potency over cyclosporine A

Source: Aurinia. Data on file.

Potential disease-modifying podocyte stabilization, which protects against proteinuria

Aurinia Studies Evaluating Voclosporin in Active Lupus Nephritis

AURION(Proof of Concept)

• Single arm, twin center exploratory study

• Biomarkers at 8 weeks: 25% reduction in UPCR. C3/C4, anti-dsDNA normalization

• N = 7

• Primary analysis: # patients achieving biomarkers and # of these patients who go on to achieve Week 24 or Week 48 remission

Completed Trials

AURORA(Phase 3 RCT)

• Phase 3

• Double blind RCT

• N = 357

• Active control

• Primary endpoint: 52 week renal response

AURA-LV (Phase 2 RCT)

• Phase 2

• Double blind RCT

• N = 265

• Active control

• Primary endpoint: 24 week renal response

• Statistically significant result in active LN patients

The AURORA Phase 3 Study Had Similar Inclusion Criteria and Primary Endpoints as AURA-LV Phase 2 Study

AURORA Study Conclusions

• The positive benefit-risk profile observed in AURORA (n=357) confirms the treatment effect seen in AURA-LV (n=265) when comparing voclosporin 23.7 mg BID in combination with background standard of care versus standard of care alone.

• The odds of achieving Renal Response on voclosporin therapy were 2.65x greater than control, while maintaining a comparable safety profile.

• Hispanic ethnicity and Black race LN patients, often severe and difficult to treat subgroups, also noted improved Renal Response with voclosporin.
